Struct WavDiff 

#[repr(C, packed(1))]
pub struct WavDiff {
    pub channel: i32,
    pub frame_offset: i32,
    pub param_id: i32,
    pub index: u16,
    pub old_val: u16,
    pub new_val: u16,
}

18-byte diff record for a single state mutation.

Every state change produces one WavDiff. The engine is the sole authority that evaluates diffs.

Layout: #[repr(C, packed)] guarantees exactly 18 bytes with zero padding. Fields are laid out as 3×i32 + 3×u16 = 12 + 6 = 18 bytes.

Fields

channel: i32

Channel index.

frame_offset: i32

Frame offset in buffer.

param_id: i32

Parameter identifier.

index: u16

Index within the channel’s state array.

old_val: u16

State value before the mutation.

new_val: u16

State value after the mutation.
